Local energy communities optimization considering cost and greenhouse gases minimization

Abstract: Local Energy Communities (LECs) facilitate consumer involvement in local electricity generation and distribution, offering a significant opportunity for society to participate in the energy transition. This paper presents the optimization of a renewable energy community in Spain, consisting of four office buildings, a collectively owned centralized photovoltaic system, and a Li-ion battery storage system. The case study assesses the performance and feasibility of the proposed solutions. The results indicate a 6% reduction in emissions and a 20% reduction in electricity costs, demonstrating the potential of LECs to enhance energy security by saving costs and emission while mitigating the vulnerability of local areas to power outages and disruptions
